An improved, delayed closing plumbing valve of the type having a cartridge with hydraulic fluid in a sealed chamber retained between an upper and lower diaphragm positioned about a longitudinally movable valve stem assembly. The chamber has a one-way piston which divides the chamber into an upper and lower section, and there is a restricted fluid flow path between the two sections. A water shut off gasket is at the base of a valve stem and has a removable gasket ring to permit the replacement of the gasket. The valve seat may also be removable for replacement. The lower diaphragm is provided with a sealed chamber to prevent its degradation by particles in the water. The diaphragms at the upper and lower end of the chamber are retained and sealed to the valve stem by retaining rings having a conical upper end which holds the inner part of the diaphragm against the valve stem. The diaphragms preferably permit the turning of the valve stem with respect to the cartridge without damage to the diaphragms.

An improved, remote controlled valve and dual push button assembly, having a hand operated push button which, when depressed and released, opens a water valve for a predetermined length of time after which the valve closes. The valve is also connected to a foot operated push button which, when depressed, holds the valve in an open configuration as long as the foot button is depressed. The improved valve and button assembly provides an air flow path through the foot button when the foot button is not depressed. The air flow path utilizes a hole in a diaphragm of the foot button which communicates with an air flow path in the base of the piston which depresses the foot button diaphragm. The disclosure also includes a check valve held in the needle valve which is a part of the timing mechanism of the hand operated button. The check valve prevents the flow of air out through the needle valve and permits air to only flow in through the needle valve.

A security sleeve for facilitating the mounting of plumbing fixtures in fire rated masonry or concrete wall construction. The sleeve has a pair of metal plates which are spaced apart about the thickness of the wall. The plates have a plurality of holes which correspond with a plurality of conduits bridging the metal plates to form passageways for plumbing pipes and fasteners connected to the plumbing fixture.

A vandal resistant security light fixture having a housing and a light which is serviceable and removable from outside the room in which it is installed. The housing has at least one surface which faces into the room and is open at the back to permit servicing or replacement of the light assembly without having to enter the room. The fixture is vandal resistant and is particularly useful in prison cells and may be provided with one or more vandal resistant switches and vandal resistant electrical receptacles.

A plumbing fixture in combination with means for preventing overflow from a toilet bowl having a P-trap when an obstruction is created in the waste outlet thereof, such plumbing fixture including a blow-out jet pipe, the entrance of the pipe being coupled in fluid communication with the water supply pipe connected to the toilet bowl at the upper portion thereof and the outlet of the pipe coupled in fluid communication with the P-trap of the toilet bowl of the plumbing fixture, comprising: a toilet bowl having a water supply pipe operably coupled therewith; an electrically-controlled flushing valve operably associated with the supply pipe for controlling the flow of water to the toilet bowl; a source of electricity for operating the valve; electrical switch means operably associated with the source of electricity for controlling the delivery of electricity for controlling the delivery of electricity to the valve for actuation thereof; an insulated electrical probe mounted in the water supply pipe; said electrical probe operably associated with a detection circuit means whereby said detection circuit deactivates said source of electricity when water is in said supply pipe and completes the circuit between said electrical probe and electrical ground.

Overflow inhibitor for plumbing fixtures

A plumbing fixture with a toilet bowl having a P-trap with means for inhibiting overflow from the toilet bowl when an obstruction exists in the waste outlet thereof, comprising: a tolet bowl having a flushing rim thereabout adapted to be coupled to a water supply pipe; an electrically controlled flushing valve for controlling the flow of water in the water supply pipe; a source of electricity for operating the flushing valve; a switch for controlling the flow of electricity to the flushing valve; a blow-out jet pipe coupled to the P-trap and adapted to be coupled to the water supply pipe; a hollow adapter having at least four openings thereinto wherein one opening is coupled to a water supply pipe, one opening is coupled to the blow-out jet pipe, and one opening is coupled to the flushing rim so that when water resides therein water also resides in the adapter via the opening coupled to the flushing rim, said adapter having a weir therein dividing the openings coupled to the water supply pipe and the blow-out jet pipe from the other openings therein; and an electrical probe mounted in the remaining opening in the adapter thereby disposing it below the top of said weir, the electrical probe being operably connected to a detection circuit, the detection circuit operating to prevent the electrical actuation of the flushing valve when water is in the flushing rim and in the adapter about the probe, and completes the circuit between the probe and electrical ground.

A plumbing installation jig and wall sleeve is provided for the secure and rapid installation of plumbing fixtures through concrete, gunite, masonry walls and the like. The device includes a single rectangular sleeve, with precisely located individual tubes for the anchor bolts which accurately position the fixture, and security bars which are attached to at least two of the parallel walls of the rectangular sleeve.
